Definitions

  • the present invention relates to a device for metering liquid water softeners into the water contained in the tank of household steam appliances such as, for example, ironing systems, steam cleaners or the like.
  • these household appliances comprise steam generating means which may be, for example, a manually filled water boiler, a self-filling water boiler or an instantaneous steam generator.
  • steam generating means which may be, for example, a manually filled water boiler, a self-filling water boiler or an instantaneous steam generator.
  • the formation of calcareous encrustations is inevitable and the latter, in addition to negatively influencing the performance of the appliance, may result in the need to replace these steam generating means or part of them.
  • the object of the present invention is to provide a device for metering liquid water softener into the water contained in the tanks of such household steam appliances which allows the supplying, in an automatic manner and at predetermined time intervals, into the water present in said steam generating means, of a certain amount of liquid water softener, metered depending on the hardness of the said water, so as to ensure constantly efficient operation of the household steam appliance and prevent or at least limit in a significant manner the formation of calcareous encrustations.
  • a device for metering liquid water softener into the water of the household steam appliances provided with steam generating means characterized in that it comprises: a storage tank containing a liquid water softening agent provided with a line for delivering this liquid into the water tank of the steam generating means; means for supplying and regulating the amount of liquid water softener drawn off via a suitable intake line from this tank, and electronic means for automatically metering the amount of liquid water softener to be supplied, co-operating with these supplying and regulating means and with these steam generating means.
  • 1 denotes a manually filled water boiler of a household steam appliance, such as, for example, an ironing system, a steam cleaner or the like.
  • This boiler comprises an intake which is supplied with water through a water supply line 2, and a steam delivery outlet 3.
  • Numeral 4 denotes a tank containing a liquid water softener, which is drawn off from this tank 4 by means of a volumetric micropump 5 provided upstream of a first intake line 6 connected to said tank 4 and downstream of a second delivery line 7 connected to the boiler 1.
  • the operation of the volumetric micropump 5 and the operating cycle of the boiler 1 is controlled by an electronic board 8.
  • this electronic board 8 detects the operating time of the boiler 1 which produces steam and, after lapsing of a certain operating time interval previously programmed on this board, depending also on the hardness of the water used, the volumetric micropump 5 is activated and draws off a certain amount of liquid water softener from the tank 4 by means of the intake line 6 and supplies it to the boiler 1 via the delivery line 7.
  • Fig. 2 illustrates the present device applied to a self-filling water boiler 1'.
  • the line 2 for feeding the water into this boiler 1' is connected by means of a pump 9 to a water tank 10.
  • This pump 9 is provided upstream of an intake line 11 and downstream of an exhaust line 12.
  • the delivery line 7 of the volumetric micropump 5 of the present metering device is connected to the water tank 10 and intercepts the exhaust line 12 of the pump 9 for feeding the water to the boiler 1'.
  • the electronic board 8 controls the operating cycles of this pump 9 and the volumetric micropump 5.
  • This electronic board 8 activates the volumetric micropump 5 which propels the liquid water softener drawn off from the tank 4 into said exhaust line 12 of the pump 9 until it reaches the water tank 10 and then the liquid water softener is mixed with the water contained in said tank 10.
  • the cycle for automatic metering of the liquid water softener is, as seen above, determined by said electronic board 8 which measures the number of cycles of the pump 9: once a certain number of operating cycles programmed on said board has been reached, said pump 9 stops and the volumetric micropump 5 is activated for a certain number of seconds. In this case, therefore, the pump 9 draws a mixture of water and liquid water softener and supplies it into the boiler 1' via the line 2.
  • Fig. 3 illustrates the device according to the invention applied to the intake line 11 of the pump 9 for automatically filling the boiler 1'.
  • the line 7 for delivery of liquid water softener intercepts the water intake line 11 upstream of the pump 9 and the latter therefore draws off water from the tank 10 mixed with liquid water softener: the mixture of water and liquid water softener is then supplied into the boiler 1' via the line 2.
  • the electronic board 8 again controls the volumetric micropump 5 and the operating cycles of the pump 9, and the cycle for automatic metering of the liquid water softener is determined in a manner entirely identical to that described with reference to Fig. 2.
  • the present device for metering liquid water softener may be applied to any steam generating means for household appliances, for example an instantaneous steam generator 13 with an automatic water filling system as shown in Fig. 4.
  • this instantaneous steam generator 13 comprises a line 14 for feeding the water to an outlet 15 for the steam produced.
  • the device for metering the liquid water softener has a constructional variation: an electrovalve 16 is envisaged in place of the volumetric pump 5. This electrovalve 16 is in fact inserted along a line 17 supplying the liquid water softener drawn off from the tank 4 to the intake line 11 of the pump 9 for feeding the water to the instantaneous steam generator 13 and is controlled by the electronic board 8.
  • This electronic board 8 also controls the number of operating cycles of said pump 9.
  • metering of the liquid water softener is performed by means of opening of the electrovalve 16 operated by said electronic board 8: the liquid water softener is drawn off by the pump 9, making use of the vacuum which is created inside the latter. As described above, the number of operating cycles of the pump 9 is programmed on said electronic board 8.
  • This electrovalve 16 could also be envisaged for the boiler 1' according to Fig. 3, where obviously the line 7 supplying the liquid water softener is connected to the intake line 11 of the pump 9, so as to make use of the vacuum inside the latter.
  • a volumetric micropump could be envisaged in place of the electrovalve 16, and this volumetric micropump would envisage, as seen for the boiler 1' according to Figs. 2 and 3, an liquid water softener delivery line 7 which could be connected to the exhaust line 12 or to the intake line 11 of the pump 9 for feeding water to this instantaneous steam generator 13.
